Building an Asymmetrical (Cruising) Spinnaker
Do you want to sew your own asymmetrical spinnaker? You’re in luck! Our how-to videos will walk you, step by step, through the process of assembling and sewing an asymmetrical (cruising) spinnaker kit from Sailrite®. At Sailrite, you can choose from our selection of popular, standard sail kits as well as custom sail kits that we will design for you to fit your boat’s specific dimensions. Once your asymmetrical sail kit has arrived, watch this video series to find out how easy it is to put it together and sew your own sail!
In this video series, we’ll be building our asymmetrical spinnaker in four parts. Follow along with our videos to see how to put yours together. Our sail plotter draws the center lines right on the sail material for you. All you have to do as align all the individual panels, baste them together using Seamstick Basting Tape for Sailmaking & Vinyl (#659) and then sew the panels together using a zigzag stitch sewing machine.
In our first video, we’re using the Sailrite® Professional 4-Point Sewing Machine to sew our spinnaker sail. We’re sewing one row of 4-point zigzag stitches per sail panel. The Professional is an industrial, full-size sewing machine that can sew 2-point zigzag, 4-point zigzag and straight stitch for the most versatile sewing experience. You don’t have to own the Professional in order to sew your own spinnaker. You can also use the Sailrite® Ultrafeed® LSZ-1 Sewing Machine to sew sails with excellent results. Since the Ultrafeed is only a 2-point zigzag stitch machine, you will need to sew two rows of zigzag stitches on each panel seam overlap. Next, we’ll show you how to assemble the Dacron reinforcement patches and install the corner ring with webbing strips.
In the second video, we start by gluing and sewing the entire patch assembly with the corner into the sail. We also install stay tapes to the sail. Again you’ll want to use a zigzag stitch to sew the patch to the top of the sail. Watch the video to see how this is done in full detail.
In the last video of this asymmetrical spinnaker series, we hand sew the corner rings to the sail. We’re using leather patches for reinforcement and using the Sailmaker’s Adjustable Palm to do the hand sewing. It involves using an awl to prepunch holes through the many layers of leather and sailcloth to get the needle through the thick assembly. Watch this video for the last part of sewing your own spinnaker.
